vIMPROVEMENT IN KITCHEN=RANGE VENTILATORS.

Specification forming part of Letters Patent No. 217,353, dated July 8,1879; application tiled May 20, 1879.

To all whom it may concern:

Be it known that I, DANIEL H. ERDMAN, of Camden, in the county of Camdenand State of New Jersey, have invented certain new and usefulImprovements in Ventilatingv Kitchen- Ranges; and I do hereby declarethe follow.y

ing to be a full, clear, and exact description 'of the invention, suchas will enable others skilled inthe art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification, in which- Figure l is a perspective of arange and chimney, showing my improvements applied thereto; and Fig. 2is a vertical transverse section of the same.

My invention has for its object to provide means for ventilatingkitchens and carrying off the odors and heat generated by ranges; and myimprovements have reference to the provision of means whereby such heatand odors are carried up the chimney or flue.

Referring to the accompanying drawings, A indicates a range of the usualor any suitable construction, and B a chimney or iiue, such as isordinarily employed for carrying off the products of combustion, suchchimney extending above the roof C of the house or apartment in whichthe range is located. A

D is a chamber, located at the base of the ilue B and colnmunicatingtherewith, and E is a smokepipe, extending from the range A, through thechamber D and flue B, to a point above the top of the latter, having acowl, c, between its upper end and the top of said flue, and being also,by preference, surmounted by another cowl, e.

F is a swinging hood or awning, designed to be made of sheet metal,located in front of the chamber D, constructed and arranged in suchmanner that when lowered or openedit projects over the range, as shown.

d d are openings on the under side of the chamber D, and dl d* are otheropenings on the front side of said chamber, above the hood F, all ofsaid openings being provided, as shown, with swinging doors ordampers,whieh,

Awhen closed, are fastened by turn-buttons or equivalent devices.

The operation is as follows: When cooking is proceeding on the range thehood F is drawn down, as shown in Fig. l, the dampers d2 opened, and thedampers d3 closed. The heat, odors, &c., arising from the surface of therange, or from the utensils thereon, meet the hood F, and are deflectedtoward the chamber lD.,entering the same through the openings d d. Thedraft in the line B, which is accelerated by the heated smoke-pipe E,carries such heat and odors swiftly up and out above the roof C.

Vhen the cooking or other operation of the range is completed thedampers or doors of openings di are opened, affording exit for thepassage of any heat or odors which may have escaped from the front ofthe range, and which have ascended into the upper part of the kitchen,the draft through such openings drawing in such heat and odors withcertainty and celerit f.

5When it is desired to place dishes on the shelf G, the hood F may beswung back or up in front of the chamber D.

This arrangement of devices for Ventilating may also be used inconnection with means for heating an apartment above the kitchen fromthe range. In such case a second pipe (shown at H in Fig. 2) will beemployed, surroundingythe smoke-pipe E and within the ilue Di This pipe,which l denominate the hotair pipe, receives its supply of air, in theusual manner, from the cellar or outside source, and has a blank upperend, 71, below the root' C, and register h in the room to be heated. lnthis arrangement the products of combustion pass up the pipe E, theheated air between pipes E and H, and .the odors, waste heat, gases,&c., between pipe H and 'llue B.

The cowl c, located below the end of pipe E, prevents the soot, Ste.,issuing from said pipe from falling back into tlue B.

W'hat I claim as my invention isl. The combination, with a range, A, and'llue B, ot' an internal smoke-pipe, E, extending from said rangethrough said flue, and to a point above the latter, said flue having communicating openings above the range for the entrance of waste heat,odors, tbc., substantially as shown and described.

2. The combination of range A, flue B, chamber D, having openings d, andsmokepipe E, substantially as shown and described.

3. The combination, with rango A, flue B, and smoke-pipe E, of hood F,located above said range, and adapted to deiect escaping heat, odors,Snc., into said ue, as set forth.

4. The combination of range A, ue B, chamber D, smoke-pipe E, and hoodF, said chamber D having openings d below and other openings, d, abovesaid hood, and provided With dampers, as set forth.

5. The combination of range A, flue B, having communicating openingsabove the range,

smoke-pipe E, and hot-air pipe H, whereby separate conduits are providedfor the products of combustion7 heated air, and waste heat, odors, 8m.

In testimony that I claim the foregoing I have hereunto set my hand this16th day of May, 1879.
